Description

[Technical field]

[0001] This application relates to the technical field of electrical accessories, and in particular to power outlet devices. [Background technology]

[0002] An outlet device is adapted to be fitted with a plug device to connect to a power line. Since it is necessary to accommodate the blades of the plug device, a certain amount of accommodation space must be provided in the outlet device, and thus it is difficult to significantly reduce the dimensions of the outlet device. For example, the minimum length, width and height dimensions of an outlet device that are applicable to Chinese, American and Japanese standards are approximately 24.5 mm. It is clear that such dimensional restrictions have a negative effect on the portability of the outlet device.

[0003] In view of the above circumstances, it is therefore desirable to provide an outlet device that solves at least part of the above problems. Summary of the Invention

[0004] The present application discloses an outlet device, the outlet device comprising: A base having an internal storage space; a movable cover that is movably mounted on the base along a first direction between a use position and a storage position and that at least partially extends from the base when in the use position; a receptacle located in one of the base and the movable cover, the receptacle being adapted to mate with a blade of a plug device; The plug includes a drive assembly that is installed in the storage space, is connected to the movable cover, and switches the movable cover from the storage position to the use position when the plug device is inserted, and returns the movable cover to the storage position when the plug device is removed.

[0007] In the following description, many specific details are provided to make the present application more thoroughly understood. However, as is apparent to those skilled in the art, the present application's embodiments can be implemented without one or more of these details. In other examples, some technical features known in the art are not described to avoid confusion with the present application's embodiments.

[0008] Detailed structures are provided in the following description in order to thoroughly understand the embodiments of the present application. Obviously, the implementation of the embodiments of the present application is not limited to specific details well known to those skilled in the art.

[0009] In order to at least partially solve the above-mentioned technical problems, as shown in Figs. 1A to 2B, the outlet device according to the present application comprises: A base 100 having an internal storage space; a movable cover 200 that is movably mounted on the base 100 along a first direction D1 between a use position P1 and a storage position P2, and that at least partially extends from the base 100 when in the use position P1; a receptacle 211 located in one of the base 100 and the movable cover 200 and adapted to receive the plug blade 1010 of the plug device 1000; The plug device includes a drive assembly that is installed in the storage space, is connected to the movable cover 200, and switches the movable cover 200 from the storage position P2 to the use position P1 when the plug device 1000 is inserted, and returns the movable cover 200 to the storage position P2 when the plug device 1000 is removed.

[0010] The outlet device of the present application is provided with a drive assembly that allows the movable cover 200 to be switched from the storage position P2 to the use position P1 as the plug device 1000 is inserted, and to return to the storage position P2 as the plug device 1000 is unplugged. Therefore, when the plug device 1000 is inserted, the movable cover 200 moves to the use position P1 to surround the plug blades 1010 of the plug device 1000, thereby realizing the normal power supply function of the outlet device while preventing the plug blades 1010 from being exposed, thereby improving safety. After the plug device 1000 is unplugged, the movable cover 200 moves to the storage position P2, which allows the thickness of the outlet device to be thinner than conventional outlets, improving comfort of use and making it easier to store and carry.

[0011] Hereinafter, a detailed structure of an outlet device according to an embodiment of the present application will be described with reference to Figures 1 to 7. The technical features of each embodiment of the present application can be combined with each other on the premise that there is no collision.

[0012] As known to those skilled in the art, a power outlet is a device having a receptacle for plugging in an electric cable to connect to a power line. Common receptacles include a standard three-hole receptacle, a standard two-hole receptacle, a USB receptacle, etc. In the following and in the drawings, a standard three-hole receptacle is taken as an example to describe the power outlet of the present application, but other types of standard three-hole receptacles are also applicable to the present application.

[0013] 1A and 1B show a schematic diagram of an outlet device according to the present application, and also show a plug device 1000 that plugs into the outlet device. As shown in FIG. 2A, the outlet device is illustrated as a multi-tap outlet with multiple sets of outlets 211 and has a power cord 104 shown. However, as can be appreciated, in other embodiments not shown, the outlet device may only have one set of outlets 211 and / or may not have an extended power cord. The outlet device according to the present application is preferably a portable outlet, i.e. it can be moved from one location to another before or during use. For example, the outlet device according to the present application may be a so-called plug board.

[0014] The outlet device may further have at least one type of USB interface for powering, for example, a mobile phone, a tablet computer, etc., the type of the USB interface including, but not limited to, a USB-A interface, a USB-C interface, etc.

[0015] 1A and 1B, when the plug device 1000 is fully inserted into the outlet device and the power circuit is turned on, according to the present application, a part of the outlet device is displaced in this case to increase the internal volume of at least the plug device, providing enough space to accommodate the blades 1010 of the plug device 1000. This structure can significantly reduce the volume of the outlet device according to the present application compared to conventional outlet devices.

[0016] To provide such a storage space, in one embodiment, the outlet device includes a base 100 and a movable cover 200. The base 100 has a storage space therein for accommodating electrical components, such as electrical connectors, as known in the art.

[0017] In one example, the outlet device of the present application further includes a movable cover 200 attached to the base 100 and movable relative to the base 100 along a first direction D1 between a use position P1 (see FIGS. 1A and 1B) and a storage position P2 (see FIGS. 2A and 2B). When in the use position P1, the movable cover 200 at least partially extends from the base 100 to completely store the blades 1010 of the plug device 1000 in the outlet device, and at this time, the outlet device is in a use state. As shown in FIGS. 1A and 1B, a portion of the movable cover 200 in the use position P1 extends from the base 100. In one example, when the outlet device is in the storage position P2, the movable cover 200 does not extend from the base 100, thereby reducing the dimensions when the outlet device is not connected to the plug device 1000, i.e., when the outlet device is in the unused state, or when the outlet device is in the storage position P2, the dimension by which the movable cover 200 extends from the base 100 is smaller than the dimension by which the movable cover 200 extends from the base 100 when the outlet device is in the use position P1. Preferably, when the outlet device is in the storage position P2, the movable cover 200 is flush with the surface of the base 100 such that the outlet device has a substantially flat outer surface, making it easy to carry and transport.

[0018] 1A, 1B, 2A, and 2B, when the movable cover 200 is in the use position P1, the maximum dimension of the outlet device along the first direction D1 is a first dimension DP1, and when the movable cover 200 is in the storage position P2, the maximum dimension of the outlet device along the first direction D1 is a second dimension DP2, and the first dimension DP1 is larger than the second dimension DP2. That is, by making the volume of the outlet device in an unused state smaller than the volume of the outlet device in a used state, it is possible to enable the blade 1010 of the plug device 1000 to be fully inserted and to reduce the space occupied by the outlet device. Considering that the case of the outlet device has a certain thickness to maintain its strength, it is preferable that the second dimension DP2 is 70% or less of the first dimension DP1.

[0019] In order to make the structure of the outlet device as compact as possible, the first direction D1 in which the movable cover 200 moves is preferably parallel to the direction in which the plug device 1000 is inserted into the outlet device. Therefore, the first dimension DP1 and the second dimension DP2 of the outlet device can be exemplarily described by the dimensions of the blades 1010 of the plug device 1000. Preferably, the first dimension DP1 is greater than the length of the blades 1010, and the second dimension DP2 is less than the length of the blades 1010, for example, the second dimension DP2 is less than 24.5 mm. For example, for the standard three-hole socket 211 shown in the figure, the length of the blades 1010 of the corresponding standard three-pin plug is a minimum of 18 mm, so the first dimension DP1 is greater than 18 mm, and the second dimension DP2 is less than 18 mm. That is, the height of the length, width, and height dimensions of the outlet device in an unused state is less than 18 mm. Also, for example, for a standard two-hole socket 211 (not shown), the length of the blade 1010 of the corresponding standard two-pin plug is at least 16 mm, so the first dimension DP1 is greater than 16 mm, and the second dimension DP2 is less than 16 mm. That is, the height of the length, width, and height of the socket device in an unused state is less than 16 mm. The second dimension DP2 of the socket device according to the present application is preferably less than 18 mm, more preferably less than 17 mm, and even more preferably less than 16 mm. For reference, the height of the length, width, and height of a conventional socket device having a standard three-hole / two-hole socket is generally within a range of 24.5 to 30.0 mm, so the height of the socket device according to the present application is significantly smaller than that of the conventional socket device, so that the space occupied by the socket device as a whole can be reduced, and portability can be improved. However, the above numerical values ​​are merely examples, and the dimensions of the socket device according to the present application are not limited to the above numerical ranges.

[0020] In order to ensure that the outlet device can normally supply power to the plug device 1000, the outlet device further includes a socket 211, which is located on one of the base and the movable cover and is compatible with the plug blades of the plug device; thus, the plug blades of the plug device can enter and exit the accommodating space of the base through the socket, thereby electrically connecting with the electrical elements in the accommodating space, and realizing the function of supplying power to the equipment connected to the plug device through the outlet device.

[0021] In one example, referring to Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B, the socket 211 of the outlet device is located on the panel part 210 at the top of the movable cover 200, and the panel part 210 has a surface that can contact the plug device 1000. For convenience of explanation, the panel part 210 on which the socket 211 is installed is shown to be located at the top of the outlet device, that is, the plug device 1000 is inserted downward into the outlet device through the socket 211 at the top. In other words, according to this embodiment, the plug device 1000 is inserted downward, and the movable cover 200 of the outlet device moves upward to provide an accommodation space for the plug blades of the plug device. As can be understood, the orientation terms such as "top", "upward" and "downward" used herein are changed according to the specific use position of the outlet device.

[0022] The outlet device of the present application further includes a drive assembly 10 that is installed in the storage space and connected to the movable cover 200 so that the movable cover 200 can be switched between the use position P1 and the storage position P2 along the first direction as the plug device is inserted and removed, and the drive assembly 10 switches the movable cover 200 from the storage position P2 to the use position P1 as the plug device is inserted and returns the movable cover 200 to the storage position P2 as the plug device is removed.

[0023] The drive assembly may be realized based on the members shown in Figs. 3 to 6 or in other suitable manners. An exemplary drive assembly will be described below with reference to Figs. 3 to 6. With reference to Figs. 3 and 4, the drive assembly 10 includes a floating member 400, which is located inside the movable cover 200 and faces the socket 211. When the plug device 1000 is inserted into the socket 211, the blades 1010 of the plug device 1000 abut against the floating member 400 and apply a force to the floating member 400 in a direction away from the socket 211, so that the floating member 400 slides in a direction away from the socket 211 as the plug device 1000 is inserted. Optionally, the floating member 400 may include an elastic member, which may be a member made of an elastic material. Optionally, the sliding direction of the floating member 400 may be parallel to the insertion direction of the blades.

[0024] In order to limit the sliding direction of the floating member 400, for example, to limit the floating member 400 to sliding along a first direction D1, in one example, a first guide groove extending along the first direction D1 is provided in the accommodation space of the base 100, and the floating member 400 is arranged to slide along the first guide groove, i.e., it can slide back and forth along the direction defined by the first guide groove.

[0025] Continuing with reference to Figures 3 and 4, the drive assembly 10 includes a transmission assembly connected to the floating member 400 and the movable cover 200, which drives the movable cover 200 to the above-mentioned use position when the floating member 400 slides away from the receptacle.

[0026] The transmission assembly 600 includes a first transmission member, a second transmission member and a direction-changing transmission member, the first transmission member being connected to the movable cover 200, the second transmission member being connected to the floating member 400, the direction-changing transmission member being rotatably connected to the support base 300 around a rotation axis 350 that is perpendicular to the first direction D1, and both sides of the direction-changing transmission member facing the rotation axis 350 are rotatably connected to the first transmission member and the second transmission member, respectively, and thus the movable cover 200 and the floating member 400 move along opposite directions parallel to the first direction D1, respectively.

[0027] The direction-changing transmission member is connected to the floating member 400 and the movable cover 200, and when the floating member 400 slides away from the socket, it drives the movable cover 200 to the use position P1, and optionally, the direction-changing transmission member may include at least one gear, for example, one gear. Exemplarily, the first transmission member includes a first rack 610, the second transmission member includes a second rack 620, and the direction-changing transmission member includes a gear 630, which meshes with the first rack 610 and the second rack 620, respectively, and the length direction of the first rack 610 and the length direction of the second rack 620 are both parallel to the first direction D1, that is, the teeth of the first rack 610 are arranged along the first direction, and the teeth of the second rack 620 are arranged along the first direction D1. According to the above connection method, after the blade 1010 of the plug device 1000 is inserted into the socket 211, the blade 1010 comes into contact with the floating member 400. As the blade 1010 moves in the first direction D1 away from the socket 211, the floating member 400 also slides in the first direction D1 away from the socket 211, and the floating member 400 is connected to the second rack 620. At the connection point between the second rack 620 and a direction changing transmission member such as a gear 630, a number of teeth are arranged in the first direction D1. The teeth of the gear 630 and the second rack 620 mesh with each other, and the gear 630 and other members are connected to each other. When the floating member 400 slides, the gear 630 rotates. The rotation of the gear 630 moves the movable cover 200 connected to the first transmission member to the use position P1, i.e., drives the movable cover 200 to be ejected from the base 100. The accommodating space surrounded by the movable cover 200 and the base 100 in the use position P1 is sufficient to accommodate the blades 1010 of the plug device 1000, thereby avoiding safety hazards caused by the exposure of the blades 1010 and improving the safety and reliability of the outlet device.

[0028] In one example, the outlet device further includes a first return member 114 and a second return member 115, so that the movable cover 200 can be returned to the storage position P2 after the blade 1010 of the plug device 1000 is pulled out, a first end of the first return member 114 may be connected to the base 100, e.g., connected to an inner wall of the base, and a second end of the first return member 114 is connected to the floating member 400, so as to return the floating member 400 when the plug device 1000 is pulled out, and a first end of the second return member 115 is connected to the movable cover 200, and a second end of the second return member 115 is connected to the base 100, so as to return the floating member 400 to the storage position P2 after the blade 1010 of the plug device 1000 is pulled out. The second returning member 115 returns the movable cover 200 to the storage position P2 as the plug device 1000 is pulled out, i.e., the second returning member 115 applies a force toward the storage position P2 to the movable cover 200, thereby returning the movable cover 200 to the storage position P2 after the plug blade 1010 is pulled out. This reduces the spatial volume occupied by the movable cover 200 outside the base 100, makes the spatial volume occupied by the entire outlet device smaller, particularly the dimension in the first direction D1, improves the comfort of use and portability, and also reduces packaging and transportation costs because the thickness of the outlet device in the storage position P2 is small.

[0029] Preferably, the first return member 114 may be a spring, the second return member 115 includes a spring, the axial direction of the spring is parallel to the first direction D1, the force applied by the first return member 114 to the floating member 400 is an elastic force, the first return member 114 can abut against the floating member 400 and apply a force toward the insertion port to the floating member 400. The force applied by the second return member 115 to the movable cover 200 is an elastic force, and the second return member 115 can abut against the movable cover 200 and apply a force toward the storage position P2 to the movable cover 200. In this way, the movable cover 200 is always held in the storage position P2 and / or always tries to return to the storage position P2 unless the force of the second return member 115 is released. In other words, when not in use, the first return member 114 and the second return member 115 cooperate to prevent the movable cover 200 from extending from the base 100, so that the thickness of the outlet device can be kept small.

[0030] The arrangement of the first and second return members 114 and 115 can be described with reference to the cross-sectional view of FIG. 7. The floating member 400 further includes a groove and a protrusion installed in the groove, and the first return member 114 may abut against the floating member 400. For example, the first return member 114 may be inserted into the groove and abut against the protrusion. The movable cover 200 further includes a panel portion 210 and a support portion 220, and the panel portion 210 is formed in a generally flat shape, and the support portion 220 extends from the panel portion 210 in a first direction D1. As a result, the cross-sectional structure of the movable cover 200 is generally U-shaped. A canopy portion 230 is formed at one end of the support portion 220 away from the panel portion 210. The second returning member 115 abuts against the movable cover 200 at the canopy body portion 230, for example, the canopy body portion 230 further has a groove, and a part of the second returning member 115 is located in the groove. When installed in this manner, the second returning member 115 does not interfere with other electrical components such as an electrical connector in the base 100 of the outlet device. The number and positions of the first returning members 114 and the second returning members 115 may be reasonably set according to actual needs, for example, in the case of one movable cover 200, the second returning members 115 may be symmetrically installed on the canopy body portion 230 on the opposite side thereof.

[0031] Furthermore, since the movable cover 200 has the above-mentioned substantially U-shaped cross-sectional structure, it is possible to prevent foreign matter from entering the cavity of the base 100 while the movable cover 200 is moving. Furthermore, the eaves body portion 230 formed to protrude from the movable cover 200 has a position limiting effect, and thus the movable cover 200 is movable relative to the base 100 only between the storage position P2 and the use position P1, and does not move beyond the use position P1, thereby making it possible to prevent the movable cover 200 from escaping from the base 100.

[0032] Furthermore, Figures 5 and 6 are schematic diagrams showing the positions of the direction-changing transmission member and the floating member 400 after the floating member 400 and the movable cover 200 have returned. When the plug device 1000 is pulled out of the outlet device, the first returning member 114 applies an acting force toward the socket 211 to the floating member 400, and the floating member 400 slides upward along the first direction D1, while the second returning member 115 applies an acting force toward the storage position P2 to the movable cover 200, causing the movable cover 200 to move toward the storage position P2. During this process, the floating member 400 drives the direction-changing transmission member, such as a gear, to move the movable cover 200 toward the storage position P2, thereby returning the movable cover 200 to the storage position P2.

[0033] The inventors of the present application have found that it is particularly advantageous to overcome the action force of the first return member 114 and the second return member 115 by using the insertion force of the plug device 1000. Generally, due to safety requirements, a safety device (not shown) such as a protective gate must be installed in the outlet device, and a user needs a certain amount of force to release the safety device when inserting the plug device 1000. According to the present application, the action force of the first return member 114 and the second return member 115 is overcome by using the insertion force of the plug device 1000, so that the movable cover 200 can be moved from the storage position P2 to the use position P1. Since no additional force or any other operation is required in this process, the outlet device according to the present application is easy to use.

[0034] Taking the illustrated embodiment as an example, the plug device 1000 is inserted downward and the movable cover 200 of the outlet device moves upward. That is, in this embodiment, the plugging force of the plug device 1000 acts in the opposite direction to the moving direction of the movable cover 200. In some other examples, not shown, the socket 211 of the outlet device may be located in the base 100, and the movable cover may be installed in the base on the side opposite to the socket 211, and the movable cover 200 of the outlet device may move downward when the plug device 1000 is inserted downward. That is, the plugging force of the plug device 1000 acts in the opposite direction to the moving direction of the movable cover 200. For example, this can be achieved by installing the direction-changing transmission member to have an even number of gears. For example, the direction-changing transmission member may include a first gear and a second gear, where the first gear meshes with the floating member, the second gear meshes with the movable cover, and the first gear also meshes with the second gear, and when the floating member moves downward, it drives the first gear to rotate, and the first gear drives the second gear to rotate, and drives the movable cover to move downward to the use position.

[0035] In the drawings, only one direction-changing transmission member, for example, a gear, is shown, and in this way, it is possible to plug in the plug device 1000 and drive the movable cover 200. However, with respect to the central axis of the blade 1010 of the plug device 1000, another direction-changing transmission member, for example, a gear (not shown), may be further installed on the opposite side of the illustrated direction-changing transmission member, that is, the direction-changing transmission members may be installed on both sides symmetrically with respect to the central plane.

[0036] Up to this point, the description of the outlet device of the present application has been completed. However, it is understood that the outlet device may further include other members in addition to the above-mentioned structure, which will not be described in detail here.

[0037] As described above, the outlet of the present application is equipped with a drive assembly so that when the plug device is inserted, the movable cover can be switched from the stored position to the usage position, and can be returned to the stored position when the plug device is pulled out. Therefore, when the plug device is in the usage position, the movable cover moves to the usage position to surround the plug blades of the plug device, thereby realizing the normal power supply function of the outlet while preventing the plug blades from being exposed and improving safety. After the plug device is pulled out, the movable cover moves to the stored position, allowing the thickness of the outlet to be thinner than conventional outlets, improving comfort of use and making it easier to store and carry.

[0038] Hereinafter, the detailed structure of the outlet device according to another embodiment of the present application will be described with reference to Figures 8 to 23, and the technical features of each embodiment of the present application can be combined with each other on the premise that there is no collision. As shown in Figures 8 to 23, the outlet device according to the present application includes a base 100, a movable cover 200, a support stand 300, a floating member 400, a self-locking member 500, a transmission assembly 600 and an elastic member.

[0039] The base 100 includes an upper base 110, a lower base 120, and an accommodation space 130 located between the upper base 110 and the lower base 120, and the upper base 110 has an opening 111. The movable cover 200 has an insertion port 211, and the movable cover 200 is connected to the opening 111 movably along a first direction D1 between a use position where the movable cover 200 protrudes from the opening 111 and a storage position where the movable cover 200 retracts into the accommodation space 130, and the first direction D1 is parallel to the depth direction of the insertion port 211. The support base 300 is located in the accommodation space 130 and corresponds to the opening 111, and the support base 300 is connected to the lower base 120 and has a first guide member extending along the first direction D1 and a first locking portion extending along a second direction D2 perpendicular to the first direction D1. The floating member 400 is movably connected to the first guide member between a first position and a second position along a first direction D1, the first position being closer to the movable cover 200 than the second position, and the floating member 400 has a second guide member. The self-locking member 500 has a second locking portion that fits the first locking portion and a guide slope 520 that abuts against the blade 1010, the self-locking member 500 is movably connected to the second guide member between a locked position and an unlocked position along a second direction D2, the self-locking member 500 in the locked position causes the second locking portion to contact the first locking portion and the self-locking member 500 in the unlocked position causes the second locking portion to separate from the first locking portion, and the guide slope 52 ...3, the self-locking member 500 in the locked position causes the second locking portion to contact the first locking portion and the self-locking member 500 in the unlocked position causes the second locking portion to separate from the first locking portion, and the guide slope 520 is movably connected to the second guide member between a locked position and an unlocked position along a second direction D4, the self-locking member 500 in the unlocked position causes the second locking portion to contact the first locking portion and the self-locking member 500 in the unlocked position causes the second locking portion to separate from the first locking portion, and the guide slope 520 is movably connected to the second guide member between a locked position and an unlocked position along a second direction D The self-locking member 500 has a first end 521 and a second end 522 spaced apart along D2, and the distance from the first end 521 to the movable cover 200 is smaller than the distance from the second end 522 to the movable cover 200. When the blade 1010 is inserted into the socket 211 and contacts the guide slope 520, the self-locking member 500 drives the floating member 400 to move from the first position to the second position, and the self-locking member 500 moves from the unlocked position to the locked position.The transmission assembly 600 includes a first transmission member, a second transmission member, and a direction-changing transmission member, the first transmission member is connected to the movable cover 200, the second transmission member is connected to the floating member 400, the direction-changing transmission member is rotatably connected to the support base 300 around a rotation axis 350 perpendicular to the first direction D1, and both sides of the direction-changing transmission member facing the rotation axis 350 are rotatably connected to the first transmission member and the second transmission member, respectively, so that the movable cover 200 and the floating member 400 move along opposite directions parallel to the first direction D1. Both ends of the elastic member are connected to the floating member 400 and the self-locking member 500, respectively, to apply an acting force to the self-locking member 500 to move it toward the unlocked position along the second direction D2.

[0040] In the outlet device according to the present application, a base 100 is installed which has an accommodation space 130 inside and an opening 111 on the outside, and a movable cover 200 having an outlet 211 is installed in the opening 111 so as to be movable along a first direction D1. When the movable cover 200 protrudes from the opening 111, it is in a use position, and when the movable cover 200 retracts into the accommodation space 130, it is in a storage position. A support stand 300 corresponding to the opening 111 is installed in the accommodation space 130, and a first guide member aligned along the first direction D1 and a second guide member perpendicular to the first direction D1 are installed on the support stand 300. The floating member 400 is provided with a first locking portion and a first guide member movably connected to the first guide member along a first direction D1, so that the floating member 400 can move between a first position and a second position relative to the support base 300 along the first direction D1 and be closer to the movable cover 200 when in the first position; the floating member 400 has a second guide member, and the self-locking member 500 is movably connected to the second guide member along a second direction D2, the self-locking member 500 has a second locking portion that fits the first locking portion, and a blade 1010. When the blade 1010 is inserted into the socket 211 and comes into contact with the guide slope 520, the self-locking member 500 first moves from the first position to the second position together with the floating member 400. At the second position, the self-locking member 500 is abutted by the blade 1010 via the guide slope 520, and then moves from the unlocked position to the locked position along the second direction D2. When the self-locking member 500 is in the locked position, the first locking portion comes into contact with the second locking portion and moves in the first direction D1. and engage with each other, at this time, the movable cover 200 cannot move to the storage position along the first direction D1; further, by installing the transmission assembly 600, the moving directions of the floating member 400 and the movable cover 200 are reversed, i.e., when the floating member 400 moves to the second position, the movable cover 200 moves to the use position; and by installing an elastic member to provide an acting force for the self-locking member 500, the self-locking member 500 can automatically return to the unlocked position after the blade 1010 is pulled out.By using the above technical means, the degree of freedom of movement of the movable cover 200 to retreat along the first direction D1 after the plug device 1000 is inserted into the outlet device can be limited, thereby preventing a gap from being created between the plug device 1000 and the movable cover 200 due to incorrect operation of pressing the movable cover 200, thereby reducing the risk of electric shock and further improving electrical safety.

[0041] 10, 11 and 14, the outlet device further includes a second return member, which is connected to the movable cover 200 and applies an acting force to the movable cover 200 to move it toward the storage position along the first direction D1. After the plug device 1000 is inserted into the outlet device, the second return member is in an energy stored state, and after the plug device 1000 is separated from the outlet device, the second return member releases the elastic potential energy to drive the movable cover 200 to move to the storage position.

[0042] 8 to 16, 19 and 20, in implementing the transmission assembly 600, for example, the first transmission member may be configured as a first rack 610, the second transmission member may be configured as a second rack 620, and the direction-changing transmission member may be configured as a gear 630. The teeth on both sides of the gear 630 on the opposite sides mesh with the first rack 610 and the second rack 620, respectively. The length direction of the first rack 610 and the length direction of the second rack 620 are both parallel to the first direction D1. In the process of inserting the plug device 1000 into the outlet device, the plug blade 1010 abuts against the self-locking member 500 to drive the floating member 400 and the movable cover 200 to move away from each other. When the distance between the movable cover 200 and the floating member 400 is the largest, there is still a certain distance between the movable cover 200 and the plug device 1000. In the process of continuing to insert the plug device 1000 into the outlet device, the self-locking member 500 moves from the unlocked position to the locked position along the second direction D2 by abutting against the guide slope 520 of the self-locking member 500 until the self-locking member 500 is switched to the locked position, and at this time, the degree of freedom of the movable cover 200 along the first direction D1 is limited, so that it is possible to prevent the movable cover 200 from being pressed due to erroneous operation, causing the movable cover 200 to move to the stored position.

[0043] 10 to 14 and 18 to 20, the first guide member may include a first guide groove 310, which is recessed from a surface adjacent to the upper base 110 of the support 300 along the first direction D1, i.e., the first guide groove 310 is recessed from a surface adjacent to the opening 111 of the support 300 along the first direction D1. The external structure of the floating member 400 matches the first guide groove 310. The floating member 400 slidably fits into the first guide groove 310 along the first direction D1, and the floating member 400 in the second position abuts against the groove bottom surface of the first guide groove 310. The second guide member is configured as a second guide groove 410 recessed from one side of the floating member 400 in the second direction D2. The self-locking member 500 is slidably fitted into the second guide groove 410 along the second direction D2. The opening direction of the second guide groove 410 is the same as the direction in which the self-locking member 500 moves from the locked position to the unlocked position. A lock through hole 411 through which the second engaging portion moves along the second direction D2 is provided at the bottom of the second guide groove 410, and a first insertion notch 420 through which the blade 1010 moves and passes is provided at the side of the second guide groove 410 adjacent to the movable cover 200. During the process of inserting the blade 1010 into the outlet, the blade 1010 passes through the socket 211 and the first insertion notch 420 of the movable cover 200 in this order and then abuts against the guide slope 520 of the self-locking member 500. The degree of freedom of the self-locking member 500 to move along the second direction D2 is restricted before the self-locking member 500 reaches the bottom of the second guide groove 410, so that the self-locking member 500 drives the floating member 400 to move together with the blade 1010 by the abutting force of the blade 1010. Until the floating member 400 moves to the second position, the self-locking member 500 moves along the second direction D2 by the abutting action between the guide slope 520 and the blade 1010, so that the second locking portion passes through the lock through-hole 411 and abuts against the first locking portion, preventing the floating member 400 and the movable cover 200 from moving along the first direction D1.

[0044] After the blade 1010 is completely inserted into the outlet, it is electrically connected to the plug receptacle located in the outlet. Therefore, when the floating member 400 is in the second position and the self-locking member 500 is in the locked position, a part of the blade 1010 abuts against the second end 522 of the guide slope 520, and another part is inserted into the plug receptacle. In contrast, referring to Figures 10 to 14 and 18 to 20, in the outlet device according to the present application, the support base 300 has a second insertion notch 320 on a surface facing the upper base 110, and when the floating member 400 is in the first position, the first insertion notch 420 and the second insertion notch 320 of the floating member 400 are joined to form an insertion through hole 800 that fits the blade 1010. After the blade 1010 passes through the insertion port 211 of the movable cover 200, it enters the insertion hole 800, and the insertion hole 800 can be used to position the blade 1010. Meanwhile, during the process of continuing to insert the blade 1010, the first insertion notch 420 and the second insertion notch 320, which are spaced apart from each other, can be used to guide the blade 1010 and prevent distortion of the blade 1010.

[0045] 10 to 14 and 18 to 23, the support 300 between the two second insertion notches 320 is provided with a guide groove 340 extending along the first direction D1, and the guide groove 340 communicates with the groove of the first guide groove 310. Correspondingly, the floating member 400 is provided with a first guide block 430 into which the guide groove 340 is slidably fitted along the first direction D1. In addition, the self-locking member 500 may be provided with a second guide block 541 that fits the guide groove 340. In this way, in the process in which the floating member 400 and the self-locking member 500 move along the first direction D1, the guide groove 340 is not only configured to slidably guide and fit with the self-locking member 500 and the floating member 400 respectively along the first direction D1, but also can limit the positions of the floating member 400 and the self-locking member 500 along the third direction D3.

[0046] 10 to 14 and 18 to 20, the socket 211 of the movable cover 200 includes at least two first sockets 211a and may further include one second socket 211b, and the two first sockets 211a may correspond to the polarities of the null line and the live line of the power cord. The second socket 211b corresponds to the polarity of the earth wire of the power cord. For example, the movable cover 200 may have only two first sockets 211a to fit a plug device 1000 having two blades 1010, may have two first sockets 211a and one second socket 211b to fit a plug device 1000 having three blades 1010, or may have five sockets 211 by combining the above two forms, that is, specifically, includes two sets of sockets 211, one set of which has two first sockets 211a and the other set of which has two first sockets 211a and one second socket 211b. Correspondingly, the blades 1010 of the plug device 1000 are also divided into first blades 1011 and second blades 1012. When a normal connection between the plug device 1000 and the outlet is ensured, the blade 1010 inserted into the first socket 211a can be regarded as the first blade 1011, and the blade 1010 inserted into the second socket 211b can be regarded as the second blade 1012.

[0047] 10 to 14, the outlet device further includes a first plug receptacle corresponding to the first socket 211a. The first plug receptacle is connected to the inside of the support base 300 and is located near the moving path of the floating member 400, and both the first plug receptacle and the guide slope 520 correspond to the insertion through-hole 800. When the blade 1010 is inserted into the first plug receptacle, the blade 1010 moves from the first end 521 to the second end 522 while contacting the guide slope 520. In other words, when the blade 1010 moves from the first end 521 to the second end 522 of the guide slope 520, the blade 1010 is inserted into the first plug receptacle.

[0048] 10 to 23, in terms of realizing the locking engagement between the self-locking member 500 and the support base 300, the first locking portion of the present application may be configured as a locking hole 311 extending from a side wall of the first guide groove 310 along the second direction D2, and the second locking portion may be configured as a locking protrusion 510 protruding along the second direction D2, the locking protrusion 510 being closer to the first end 521 than the second end 522 of the guide slope 520. The engagement between the locking protrusion 510 and the locking hole 311 can reliably limit the degree of freedom of the self-locking member 500 along the first direction D1.

[0049] 10 to 14 and 18 to 23, the locking opening 311 may extend to the outer surface of the support base 300 along the first direction D1. In this manner, it is advantageous to increase the insertion depth of the locking protrusion 510 into the locking opening 311, so that the locking engagement between the self-locking member 500 and the support base 300 is more reliable and stable.

[0050] 8 to 23, the two first plug receptacles are installed at an interval along a third direction D3 perpendicular to the first direction D1 and the second direction D2. The self-locking member 500 has two guide inclined surfaces 520, and the two guide inclined surfaces 520 correspond to the two first plug receptacles, respectively. For example, the self-locking member 500 has two locking arms and a connecting part 540 connected between the same ends of the two locking arms. A second guide block 541 is installed in the center of the connecting part 540 on the side away from the locking arms. The locking arm includes a guide wedge block and a locking protrusion 510 arranged along the second direction D2, and the dimension of the outer contour of the guide wedge block is larger than that of the locking protrusion 510, so that a position limiting step is formed between the guide wedge block and the locking protrusion 510, and the position limiting step can limit the guide wedge block from penetrating the lock through hole 411. The guide inclined surface 520 is installed on the guide wedge block.

[0051] 10 to 14 and 19 to 23, the elastic member may be configured as a first compression spring 700, and the side of the self-locking member 500 facing the groove bottom of the second guide groove 410 is connected to one end of the first compression spring 700, and the other end of the first compression spring 700 is connected to the groove bottom of the second guide groove 410. For example, a first spring positioning hole 530 is provided on the surface facing the groove bottom of the second guide groove 410 of the self-locking member 500, and a first spring positioning post 412 is provided at the groove bottom of the second guide groove 410. Of course, the first spring positioning hole 530 may be provided at the groove bottom of the second guide groove 410, and the first spring positioning post 412 may be provided at the self-locking member 500. The first spring positioning hole 530 receives and positions one end of the first compression spring 700, and the first spring positioning post 412 receives and positions the other end of the first compression spring 700.

[0052] 8 to 17, in order to accurately guide the movement of the movable cover 200 when the movable cover 200 moves along the first direction D1, the outlet device of the present application further includes a third guide mechanism located in the accommodation space 130. The third guide mechanism is connected to the movable cover 200 and slidably fits into the support base 300 along the first direction D1. In another embodiment of the present application, the third guide mechanism may be slidably fitted into the lower base 120 or the upper base 110 along the first direction D1.

[0053] Further, referring to FIG. 8 to FIG. 18, the second return member is configured as a second compression spring 710. The third guide mechanism may be configured as a guide post 231 extending along the first direction D1, and the support base 300 has a guide hole 330 that fits the guide post 231. By fitting the guide post 231 and the guide hole 330, the movable cover 200 is slidably fitted to the support base 300 along the first direction D1. One end of the guide post 231 close to the upper base 110 has a second spring positioning hole 231a that fits the second compression spring 710, and the upper base 110 has a second spring positioning post 112 on its inner surface that fits the second compression spring 710. The second spring positioning hole 231a and the second spring positioning post 112 can reliably position the second compression spring 710 and prevent the second compression spring 710 from being separated.

[0054] 8 to 18, the movable cover 200 is cap-shaped, and a groove is formed on the side of the movable cover 200 facing the inside of the accommodation space 130, and the groove accommodates the support base 300 when the movable cover 200 is in the storage position. As a specific structure, the movable cover 200 has a panel portion 210, a support portion 220, and a visor portion 230. The panel portion 210 fits into the opening 111, and the insertion port 211 is provided in the panel portion 210. When the panel portion 210 is in the storage position, the panel portion 210 is flush with the outer surface of the upper base 110. The support portion 220 is configured to be formed so as to extend from the outer periphery of the panel portion 210 toward the lower base 120 along the first direction D1, and is continuously provided along the circumferential direction of the panel portion 210, and slidably fits into the opening 111 along the first direction D1. The overhanging body portion 230 is connected to the outside of one end of the guide portion away from the panel portion 210, and when in the use position, the overhanging body portion 230 abuts the upper base 110 and forms a position-limiting fit with the upper base 110 along the first direction D1.

[0055] 8 to 23, the first rack 610, the second rack 620 and the gear 630 of the present application may be provided in two pieces each. The guide posts 231 and the guide holes 330 may be provided in two pieces each.

[0056] The two first racks 610 are arranged separately on the inner walls on both sides of the movable cover 200 along the third direction D3. The two second racks 620 are arranged on both outer sides of the floating member 400 along the third direction D3, and one end of the second rack 620 close to the movable cover 200 extends and is connected to the floating member 400 along the third direction D3. The support base 300 has a notch through which the second rack 620 can slide, corresponding to the extension portion of the second rack 620, and the notch communicates with the first guide groove 310, and the dimension along the first direction D1 fits the movable range of the extension portion of the second rack 620. The two gears 630 are arranged separately on both outer sides of the support base 300 along the third direction D3. The two guide posts 231 are disposed separately on both sides of the movable cover 200 along the second direction D2 or the third direction D3, and are connected to the overhanging body portion 230.

[0057] In the outlet device according to the embodiment of the present application, a base having an opening is provided, and a movable cover having an insertion port is movably provided in the opening along a first direction, so that the movable cover is in a use position when it protrudes from the opening, and in a storage position when it retracts into the storage space. A first locking portion perpendicular to the first direction is provided in the base, and a floating member is movably connected to the base along the first direction, so that the floating member moves between a first position and a second position relative to the base along the first direction, and is closer to the movable cover when the floating member is in the first position. A self-locking member is movably connected to the base along the second direction, and abuts against a second locking portion that fits the first locking portion, and against the plug blades. The self-locking member first moves from the first position to the second position together with the floating member when the blade is inserted into the socket and contacts the guide slope, and when the self-locking member is in the second position, the self-locking member is abutted by the blade by the guide slope, and then moves from the unlocked position to the locked position along the second direction, and when the self-locking member is in the locked position, the first locking portion contacts the second locking portion to be locked and engaged along the first direction, and the movable cover cannot move to the storage position along the first direction, and a transmission assembly is further provided to reverse the movement direction of the floating member and the movable cover, that is, when the floating member moves to the second position, the movable cover moves to the use position. By using the above technical means, the degree of freedom of the movable cover to move backward along the first direction after the plug device is inserted into the socket device can be limited, so that it is possible to prevent the movable cover from being pressed by erroneous operation to generate a gap between the plug device and the movable cover, which is helpful in reducing the risk of electric shock and improving electrical safety.
